sPEoIrIcATIoN forming part bf Letters Patent mtvoaoae, dated June 10, 1902. Original application filed Ma 29, 1901. Serial No. 62,413. Divided and this application filed December 23,1901. $erial To all whom it may concern: Y

Be it known that I, JOHN R; THOMAS, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Holddown Devices for Woodworking-Machines, of which the follow ing is a specification.

This application is a division of my applil0 cation for patent on improvement in moldingmachines filed May 29, 1901, Serial No. 62,413. It is the object of my invention to provide improved means for holding the stock to the 'tableof the woodworking-machine, especially between the side heads of a molding-machine or to rear of the upper cutter-head; to provide novel means foradjusting the pressurefeet sidewise of the table and with relation to the cutter-heads and to height above the table and for hanging and permitting the swinging of the same; and myinvention consists in the'parts and in the construction, ar-

rangements, and combinations of parts hereinafter more fully described and claimed.

In the drawings, Figure 1 is an end view of myimproved device shown inconnection with so much of a molding-machine in side elevation as is necessary to illustrate my invention. Fig. 2 is a plan view of the same. Fig. 3c 3 is an enlarged plan view of my improved device. Fig. at is a side elevation of the same, showing the swinging frame in raised position in dotted lines; and Fig. 5 is a plan view of the horizontal adjustable slide.

A is the frame of the machine, B an upper cutter-head, and C D side heads. I

E represents the table or bed of the machine overwhich the stock is adapted to be fed by suitable means.

A swinging, frame 1 is pivoted on a bolt 2, taking through lugs 3 on the frame. The swinging frame is preferably bifurcated, as shown at 4, the forks extending to either side of and fitting snugly against an extension 5 of theframe. Theforksmay'haveinwardly-pro jecting lugs b, seating in seats 7 in the extension, with planed faces between the sides of the lugs and extension. A cross-piece 8 is secured to the extension by means of a (No model.)

hand-Wheel and screw 9 and is adapted to turn thereon and take snugly against the swinging framefor holding the latter rigidly in place when in normallowered operative position. "Theswingingframe has adjustably secured theretda pair of slides-11, adjustably held in position by means of bolts 12, taking through slots 13 in the slides and into the swinging frame. 'lhese'slides are adjustable transversely of the bed of the machine and at their forward ends carry slides 15, which are given an up-and-down adjustment by means of bolts 16 and held securely in place by set-bolts 17. The slides 15 carry feet 18, to which blocks 19 areadapted to be'secured,

to the'bottom of which latter'pattern-piecs I in dotted lines in Fig. 4.

I claim 1. In a woodworking-machine, a holddown device comprising in combination a swinging frame, swinging and solely supported from one side of the machine, with means for rig idly holding the swinging frame above the table of the machine, with a slide for the swinging frame, and means for adjusting the slide for extending a greater or less distance over the table of the machine from said side, and a'second slide, with means for adjusting the latter for extending a greater or less height above the table, with means for permitting c.

the swinging of the swinging frame and slides, substantially as described.

2. In a woodworking machine, a holddown device comprising incombination aswinging frameoverhanging the table of the machine from the side and supported solely from said side, with means at said side for rigidly secur ing" the swinging frame in normal overhanging position, slides for the swinging frame, with means for adjusting the slides on the swinging frame to overhang the table a greater or less distance, and second slides,with means for adjusting the latter toward or away from the table, and means for permitting the swinging frame and slides to be swung upwardly away from the table, substantially as described.

3. In a woodworking-machine, a holddown device comprising in combination a bifurcated swinging frame, and a post extending between the forks, a clamp for securing the swinging frame rigidly in position, with a pair of slides longitudinally and independently adjustable on the swinging frame, and a pair of secondary slides transversely independentlyadjustable on the latter,with means for permitting the upward swinging of the frame with the slides thereon away from the table of the machine, substantially as described.

4. In a woodworking-machine, the combi nation of a frame, a swinging frame swinging from one side of the frame and supported solely from the side of the frame from which it swings, with a pair of slides, one adjustable for extending a greater or less distance over the table of the machine from the side from which the swinging frame swings, and the other adjustable for greater or less height above said table, with said slides and means for adjusting same on said swinging frame.

In testimony whereof I have subscribed my name hereto in the presence of two subscribing witnesses.

JOHN R. THOMAS.
